The chordae tendinae in the left ventricle act as festoons and when left ventricle contracts,these help to close the mitral valve(bicuspid vale) which is between the left atrium and left ventricle.If these chordae are damaged then the closure of this valve is not perfect fit and the blood can regurgitate into the left atrium while the left ventricle is contracting.this is called mitral incompetence.This all depends on the severity of the damage.
